build
public DnsOptions.StaleDnsOptions build ()
Creates and returns the final StaleDnsOptions
instance, based on the values
in this builder.
Returns | |
---|---|
DnsOptions.StaleDnsOptions |
This value cannot be null . |
setAllowCrossNetworkUsage
public DnsOptions.StaleDnsOptions.Builder setAllowCrossNetworkUsage (int state)
Sets whether to return results originating from other networks or not. Normally, the HTTP stack clears the DNS cache entirely when switching connections, e.g. between two Wi-Fi networks or from Wi-Fi to 4G.
Parameters | |
---|---|
state |
int : one of the DNS_OPTION_* values
Value is DnsOptions.DNS_OPTION_UNSPECIFIED , DnsOptions.DNS_OPTION_ENABLED , or DnsOptions.DNS_OPTION_DISABLED |
Returns | |
---|---|
DnsOptions.StaleDnsOptions.Builder |
the builder for chaining
This value cannot be null . |
setFreshLookupTimeout
public DnsOptions.StaleDnsOptions.Builder setFreshLookupTimeout (Duration freshLookupTimeout)
Sets how long (in milliseconds) to wait for a DNS request to return before using a stale result instead. If set to zero, returns stale results instantly but continues the DNS request in the background to update the cache.
Parameters | |
---|---|
freshLookupTimeout |
Duration : This value cannot be null . |
Returns | |
---|---|
DnsOptions.StaleDnsOptions.Builder |
the builder for chaining
This value cannot be null . |
setMaxExpiredDelay
public DnsOptions.StaleDnsOptions.Builder setMaxExpiredDelay (Duration maxExpiredDelay)
Sets how long (in milliseconds) past expiration to consider using expired results. Setting the value to zero means expired records can be used indefinitely.
Parameters | |
---|---|
maxExpiredDelay |
Duration : This value cannot be null . |
Returns | |
---|---|
DnsOptions.StaleDnsOptions.Builder |
the builder for chaining
This value cannot be null . |
setUseStaleOnNameNotResolved
public DnsOptions.StaleDnsOptions.Builder setUseStaleOnNameNotResolved (int state)
Sets whether to allow use of stale DNS results when network resolver fails to resolve the hostname.
Depending on the use case, if the DNS resolver quickly sees a fresh failure, it may be desirable to use the failure as it is technically the fresher result, and we had such a fresh result quickly; or, prefer having any result (even if stale) to use over dealing with a DNS failure.
Parameters | |
---|---|
state |
int : one of the DNS_OPTION_* values
Value is DnsOptions.DNS_OPTION_UNSPECIFIED , DnsOptions.DNS_OPTION_ENABLED , or DnsOptions.DNS_OPTION_DISABLED |
Returns | |
---|---|
DnsOptions.StaleDnsOptions.Builder |
